The Bruins outshot the Senators 32-29 through three periods. Neither goalie had to be spectacular in the extra session, each making three saves.

The Bruins fell behind 2-0 but began to claw back in the last minute of the first period when enforcer Shawn Thornton took what looked to be a harmless wrist shot at the Ottawa net from the right wing boards. The puck managed to slip through Lehner for Thornton's second goal of the season.

Boston tied the game near the midway mark of the second when Krejci sent Daniel Paille in for a clear breakaway. Paille's snap shot beat Lehner on the stick side.

In the first minute of his first game back after missing 18 with what was diagnosed as migraines, Guillaume Latendresse broke in alone on Rask and deked the goalie to the ice before flipping the puck into the net. It was Latendresse's first goal since Dec. 11, 2011, when he was with the Minnesota Wild.

Less than seven minutes later, Turris also broke out of a lengthy slump, cutting through the slot and beating Rask with a wrist shot high to the glove side for his first goal in 22 games. It was his fifth goal of the season.
